METHOD AND APPARATUS FOR CLEANING MOLDS USED IN THE GLASS FABRICATION INDUSTRY

摘要

Graphite-like material is removed from metal molds used in the glass fabrication industry by placing a metal glass-fabricating mold with graphite-like material deposited thereon in a chamber, providing an oxygen rich mixture of combustible gases in the chamber, and igniting the oxygen rich mixture of combustible gases in the chamber to produce a high temperature and a pressure wave. A high temperature wave front and a pressure wave impinge on and remove graphite-like material from the metal mold by ablation of the graphite-like material.
